Steps

In a large bowl, mix a brine of the water and salt. Mix well to thoroughly dissolve salt. Add the cabbage and daikon radish. Cover with a plate or other weight to keep the vegetables submerged. Soak for 12 hours.

Drain the brine from the vegetables, reserving the brine. Taste the vegetables for saltiness. If they are too salty, you can rinse the vegetables. If they are not salty enough, sprinkle with a little more salt (one quarter teaspoon at a time).

Put the whole mix into a jar or crock. Pour the soaking liquid over the vegetables, making sure that they are completely submerged in liquid.

Cover loosely with a clean cloth and set aside for three to seven days. The ideal room temperature to help with the fermentation is around 70 degrees Fahrenheit. If it is colder, the fermentation takes longer.

Check the kimchi daily. Make sure the vegetables stay covered in brine. After three to seven days, the kimchi will taste ripe. Once this happens, place in glass jar in the refrigerator. It will keep for months. Enjoy!
